Hi, We are going to use akka-persistance for our application and we are running our things on ec2, I tried to start PerformanceSpec on m1.medium instance, it gives ~ 10k persistent commands per sec (but actually test fails).
Also tried to start this spec on basic DigitalOcean (512RAM, SSD) instance, it gives ~ 20k persistent commands per sec, so looks like disk io is a bottleneck here. https://gist.github.com/whiter4bbit/9609930 - output for DO instance https://gist.github.com/whiter4bbit/9610488 - output for ec2 m1.medium instance.
